I see a lot of high-school and middle-school age Makaylas of various spellings, what with graduation announcements and school honor-roll listings in the paper. It definitely doesn't seem to be as popular as it was twelve or so years ago, but I'm surprised it's as far down as it is now.
It's our daughter's middle name. My husband suggested it, having seen it someplace. I liked it too. If I had it to do over I might suggest the Mikayla spelling, for no special reason. I don't care for Michaela, it just doesn't look as nice even though it's the original and closest to Michael, which it's a feminine form of. (My husband's mn is Michael, but that wasn't why he chose it.)
